Answer:

y = - 4x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 and c = - 1, thus

y = - 4x - 1 ← equation of line

In a slight hurry thanks for all the help!

julsineya [31]

Answer:

10.

Step-by-step explanation:

AK = KB so

3x + 1 = 1/3 x + 9

3x - 1/3 x = 9 - 1 = 8

Multiply through by 3:

9x - x = 24

8x = 24

x = 3

So AK = 3(3) + 1 = 10.
